REED FOR WEAVING LOOMS.

Application led September 24, .1920., Serial No. 412,573.

To all whom t may concer/n:

Be itknown that I, CHRISTOPHER T. 'Melon a citizen of the UnitedStates,residinofat Appleton, county of Outagamie, and Sbtate of Wisconsin, haveinvented new and useful Improvements in Reeds for Weaving Looms, ofwhich the following is a specilication.

This invention relates to improvements in reeds for weaving looms. i

Objects of this invention are to improve the construction of reeds forloomsgto provide a reed in which the dents are individu-- ally removablewithout necessitating the disassembling of the entire reed; to provide areed in which the correct spacing of the dents is insured, even when anew dent replaces an old dent;rto provide a reed'in which the dents arenot crowded toward their central portion; and to providea reed in'whichthe clamping pressure on the dents maybe varied. Y j

ther objects of this invention are to provide a reed in whichfaultysthreading thereofmay be corrected by the insertion or removal ofa dent without necessitating a rethreading of the reed; and to provide areed in which the inspection, removal, or correction of any defectiveand readily made. j

In the drawings Figure 1 is a fragmentary elevation of a reed.

Figure 2 is a'sectional view on line 2 2 of Figure 1.

Figure 3 is a fragmentary section on the line 3-3 of Figure 1.- s,

Figure 4 is a view of one of the dents detached. y y j Figure 5 is asimilar view of one of the dent may be quickly The reed comprises upperand lower reed bars indicated generally by the Lreference characters 1and 2, and end members 3. Between these upper and lower reed bars aseries of dents 4: are positioned in. spacedrelation by means cfa seriesof spacers 5. The

means for clamping the dents and spacers inl position comprises the bar6 which is inwardly pressed by means of a pair of screws 7 and 8 havinglocking nuts 9 and 10, respectively, such screws'passing thru and vbeingthreaded tothe end bars 3, 'their ends seating in sockets 11 and 12formed in the clamping bar 6.

y corresponding to metal, and l notches 25 adapted to engage the ribs'16 and The reedbars areeach composed of1rr1` er uV ybers 13 and 14-formed integrally and extending at substantially right angles to eachother.. TheV member 13 is provided'with a dove-tailed groove 15, andthemember v14- with an inwardly projecting V-shaped rib their length, The'v16 extending thruout j reed bars Ifurther comprise retainers in theinwardly projecting V-shaped ribs 1,8 aligning with the ribs 16. Theseretaining plates are secured to the member 13by means of j form ofplates 17, which are provided with 5 screws 19 countersunlr in the`plate l7gand i is to be done are of extremely thin metal;v

These thantheV distance between then upper and lower surfaces 21 and 22of the members l and 2, and are provided with notches 23;`

I 'the V-shaped ribs 416 and 18 of the reed bars 1 and 2. Thus when thedentsl are positioned within the reed bars and the retainers 17 aresecured inposition, the dents are carried by the V-shaped ribs 16 and`v17 formed upon the `reed bars 1 and 2. Itsends are spaced from thesurfaces 21 and22. -v 4 H Figure 5 shows a spacer 5, which is formed ofksimilar flat, vrelatively wide, 'is Y `provided with V-shaped 17, andarefurther provided vwith la dovetail projection 26 whichis adaptedtoengage within either of the dove-tailed grooves 15 formed :inthemembers 13 of the reed j bars.r

Thus itv will be seen that whenthefspacer strips .are` positioned withthe projections 26 Aslidably held within the dove-tailed grooves 15 andthe dents positioned with.; the projections 416` and 18 engaging in thenotches 23, such dents may be readily removed or replaced by removingtheretainers 17, and withdrawingv the dentfwithout danger of thevcorresponding spacer strips dropping out ofposition. v

.The'end members 3 may conveniently be formed of rectangular metalpieces-having projectingpins 27 ormedeither integrally therewith orformed separately and inserted into openings within such rectangularmembers 3. These ypins 27 are adapted to.k

plates 4 are of slightly less length engage openings 28 formedin themembers,y

iar members 3 are further provided with openings thru which' screws 29pass, such screws being countersunk in the members 3, and threaded intothe members 14 of the reed bars 1 and 2. Thus a secure and accuratepositioning of these end members 3 is secured by this method ofattachment. Either one or both of the end members 3 may be provided withthe adjusting clamping screws 7 and 8.

The clamping bar 6 is of the same width and length as the dents 4, andis correspondingly provided with notches 30 which engage the V-shapedprojections 16 and 18 of the upper and lower reed bars and freely slidethereon.

It will be seen that when the clamping Screws T and 8 are tightened, thepressure lis transmitted thru the claming bar 6 to the spacers 5, and tothe dents 4. By this construction any pressure that is desired may beplaced upon the dents 4t, and also this pressure may be quickly removedby loosening the screws 7 and 8. When these screws are loosened it willbe notedthat the ends thereof may be disengaged from the sockets 11 andl2 formed in the clamping bar 6. Upon removal of the retainers 17 thebar 6 may be completely removed if desired; also the dents may bewithdrawn by a direct lateral motion. If desired the spacers may beslipped out from engagement with their dove-tailed slots into the spaces31 at the ends of the reed bars and thereafter removed.

By this construction when any of the reed dents become broken they maybe readily removed and other dents may be substituted therefor withoutdismantling the entire reed; yalso any fault in threading may bevcorrected by a proper substitution, removal or addition of dents toeffect the desired spacing of the weft.

YVhile this reed is particularly suited to weaving wire, it is to beunderstood that the scope of this invention is not to be limited, exceptas defined in the following claims.

I claim 1. In a reed, the combination with alternate dents and spacers,of a reed bar grooved to receive said dents and provided with a recessadapted to receive said spacers, and a retaining element associated withthe bar and adapted to secure the dents thereto,

said spacers being independently' interlocked with'the barl within saidrecess.

2. In a reed for a loom, the combination with an L-shaped reed bar, of aretainer adapted to be secured to said reed bar, dents adapted to beheld in operative position by said retainer, and spacers having meansadapted to engage said bar independently of said retainer, whereby saiddents'ma'y be separately withdrawn upon removal Of' thev retainer.;

3. In a reed for a loom, the combination with a reed bar having a rib,of dents having notches adapted to register with said rib, a retaineradapted to be secured to said reed bar, and spacers interposed betweensaid dents adapted for interlocking engagement with said reed barindependently of said retainer. A

4.
